66 461 Press In Stud Question

I wish to personally thank everyone...Joe, Dick, Michael, JR, Clem, and Rob who have replied to Craig's post about my car. Your wisdom and advice is truly amazing and greatly appreciated. Last but not least, I want to thank Craig.
Best regards...Dave

PS. I was 100 yards from my house when this happened. Rather be lucky than good!!!

Re: if a exhaust rocker fails

Craig,

We're going to miss you in Florida! We'll hold the can high and present a salute in your honor.

Here's another wrench thrown into the head problem. IF you are going to the trouble of replacing the studs, you will want to use hardened guide plates and drill out the push rod holes in the old 461's. Much too much machining with the heads on the car. Hey, after all it's Dave's money and I'm sure he wants the best. Give him my regards.

Re: 66 461 Press In Stud Question

Sorry to hear you will not be at HBB.

I am very surprised that you didn't talk Dave into putting a Big Block in there!

I have tried the freon trick and Dick is very correct. They make the neatest sound when the stud warms up and splits the boss.

Thread in studs are the way to go. Do the job once.

You will me missed at HBB/Old Town.

In the time it took me to read all these...

...great posts, you could have had the heads sitting on the bench. Dave, that's just a thought from your highschool graduating classmate. Best, Dennis

Re: 66 461 Press In Stud Question

Thx AC - I wish I could come. I am going to be in Wilmingon DE and Columbus OH that week, MUCH colder. I AM going to be at Dallas on Feb 11 for the summit.....were you planning to be there?? If so, see you then!....Craig

Re: if a exhaust rocker fails

Hey JR - sorry I will miss that HBB BLAST! I am in Wilmingon DE and Columbus OH that week and weekend working....YUCK.

I agree if we go to the hassle of installing hardened guideplates etc that is way too much work on the car. However, just the threaded studs should control the tendency to pull out. I am helping him with the work, and he is moving houses right now plus my time is limited, so I am hoping we can avoid yanking the heads. First though, we need to check the cam lobe for lift, if that is bad this is all moot and they may as well come off if a cam needs to be removed....thx!....Craig

Hey JR - you met Dave at Bloomington this year, he was the tall silver haired retired air force pilot with the buddy that bought a set of midyear sidepipes from you!! ....Craig

Heeey Dennis...You know ......it takes time to compile the maximum wisdom and knowledge from this August group.
Cheers...Dave

Old Hot Rod Trick

Just drill each stud boss and pin them.

Of course, about half way through he will decide that pulling heads and having them converted to screw in would be easier.

Re: Old Hot Rod Trick

Mike - I did see the pin alignment tool in the Goodson catalog....but we will probabaly go with screw in studs.....Craig

Re: Old Hot Rod Trick

the studs are case hardened and you need a good quaility drill bit to drill them.

Re: 66 461 Press In Stud Question

I bought a set of these heads a number of years ago and upon closer inspection discovered each stud had a small weld at the boss. I have never before or since seen, heard or read of anything like this being done to press-in heads. I checked height, etc, and all seemed fine using just a straight edge and the welds appear to be done by someone that knows how to weld. I'm no welder, but it seems odd to me to try and weld between a (steel, right?) rocker stud and a cast iron boss. Again, it does not look like Bubba did it - definitely looks to be done by someone that knows welding. Never have used them ...

no problem welding cast iron to steel

do it all the time with oil pump pickup into the cast iron pump body. just use a TIG welder but the cast iron better have all the oil out of it and with new parts this is not a problem. i never tried a part that was soaked in oil like used heads

Re: no problem welding cast iron to steel

If you really don't want to pull the heads to repair the stud problem the fix clem mentions - threaded replacement stud - is the best way to go, IMO. All you will need is the correct size tap to effect the repair. A little locktite on the stud threads as the stud is tightened down and you are good to go. Years ago I replaced all the pressed-in factory studs in my heads with the non hex style straight threaded studs. These worked out just fine - no problem or worries about pulled stud/s.
